Sony on Tuesday announced its first e-book reader with built-in wireless capability. The new Reader Daily Edition offers an integrated 3G wireless connection, allowing it to access Sony's online bookstore as well as yet-to-be-announced newspaper and magazine subscriptions. The unit--which boasts a 7-inch touch screen (displayable in portrait or landscape mode)--will sell for $399 when it debuts in December. Wireless service is provided by AT&T with no direct charge to the customer.

It looks like Sony has learned a lot from the Kindle, which was a big hit mostly because the built-in wireless capability made it much more user-friendly.
